Seems pyserial has changed, adding hardware flow.control bools to link.py seems to fix the issue.

I had this same issue and switching from the 'master' to 'dev' branches fixed the problem. I suggest the 'dev' branch should be merged to master ASAP to save others from falling in this trap (it cost me an hour).

Also, since this bug is fixed this issue should be closed.
